Journalists in London

Hey all, I am moving to London in the middle of July to try my hand at some freelance writing. I was wondering if anyone has had experience freelancing in London, and how the media industry as a whole fares for foreigners. Further, has anyone had experience working for a newspaper or other type of publication that would be able to offer me some employment tips? Or hell, if you are simply willing to meet up for a pint and talk about the industry, I am game.
